Product Description
The TriQuint TGA1172-SCC is a three stage
HPA MMIC design using TriQuint’s proven
0.25 um Power pHEMT process. The TGA1172
is designed to support a variety of millimeter wave
applications including point-to-point digital radio
and LMDS/LMCS and Ka band satellite ground
terminals.
The three stage design consists of a 600um input
stage driving a 2 x 600um interstage followed by a
4 x 600um output stage.
The TGA1172 provides 29 dBm nominal
output power at 1dB compression across
27-32GHz. Typical small signal gain is 16 dB
with typical Input/Output Return Loss of <-10dB.
The TGA1172 requires minimum off-chip
components. Each device is 100% DC and RF
tested on-wafer to ensure performance
compliance. The device is available in chip form.
Primary Applications
• Point-to-Point Radio
• Point-to-Multipoint Communications
• Ka Band Sat-Com
